Patent No. 428,772, dated May 27, 1890. serial Natlaoefi. (No model.)

To all whom it may concern:

Be it known that I, PHILIPP GoLDscHMIDT, of Paterson, in the county ofPassaic and State of New Jersey, have invented a certain new and usefulImprovement in Warping -Machines, of which the following is aspecification.

My improvement relates to machines employed for warping, and isparticularly adapted to the warping'of silk.

I will describe my improvement in detail, and then point out the novelfeatures in claims. K

In the accompanying drawings,Figure l is a side elevation of a machineembodying my improvement. Fig. 2 is a plan or top view of the same. Fig.3 is a side elevation, on an enlarged scale, of a portion of themachine, looking from the opposite side to that shown in Fig. l. Fig. 4is a horizontal section of the indicator shown in Fig. 3, taken on lineFig. 5 is a detail of acertainportion of a stop mechanism which may beemployed, and looking in the direction of the arrow, Fig. 3. Fig. 6 is adetail of a modification which may be employed. Fig. '7 is a detailview, on an enlarged scale, of a portion of a stop-motion which Iemploy.

Similar letters of reference design ate corresponding parts in all thefigures.

In carrying out my improvement Itake the threads from an ordinary creelin the usual manner, and after passing them through a reel deliver themonto ahorizontally-arranged drum. After leaving the drum vthey pass to avertically-arranged spool. In passing over the drum they cause therotation of the latter by friction. The drum drives indicator meehanismby which the number of yards passing to the spool are measured. Thespool has a reciprocating motion imparted to it and may be rotated withvarious speeds. When the spool has been properly filled, a stop-motionoperates to stop the machine.

I will first describe the passage of the thread to and over the drum andthe operation of the indicator mechanism.

A thread A is delivered to a reed A from a creel of ordinaryconstruction (not shown) and in the usual manner. It passes afterleaving the reed over glass rods a. Alternate threads pass over andunder said rods, so as to cross each other in a well-known manner. Fromthe rods d the threads pass beneath a rod ct and thence onto and overthe drum B.

The drum B is journaled, as at a2, inbraekets B', extending upwardlyfrom the frame B2 of the machine. The'threads in their passage over thedrum impart rotary motion thereto by friction.

Upon the shaft of the drum is mounted a worm 19, which worm meshes withawormwheel 1)', mounted in a vertically-extending shaft 192, journaled.in the frame B2, and also in a bracket B3, extending upwardly from saidframe. The upper end portion of the shaft 192 carries a worm 193, whichworm meshes witlra worm-wheel 196, mounted upon a shaft b5, j ournaledin the bracket B3.

On the shaft 195, as shown more clearly in Fig. 4, is loosely mounted adisk 197, provided with a hub 19S surrounding said shaft. The worm-wheel19G is keyed upon said hub, and therefore when rotated imparts rotarymotion to the disk l' about the shaft 195, which latter is a stub-shaft.

C designates an indicator-dial. This dial is scored upon its face andnear its periphery to indicate the number of yards of thread which it isdesired to wind upon a spool. This dial is loosely mounted on the shaft195. It is, as shown, provided with a flange 199, which incloses thedisk 197. I prefer to ar rango between the disk 19'I and the dial C awasher of leather or similar material 1910.

C designates a hollow clamping-nut having a screw-threaded engagementwithaboss c upon the shaft 195. This clamping-nut may be rotated toforce the dial C into close con-` tact with the washer 1910, or with thedisk 197 should the washer be omitted. The dial will then rotate byfrictional contact with the disk 1J7 when the latter is rotated. Asetscrewb, engaging the outer' end of the shaft 195, may be employed tomaintain the clamping-nut in position.

The figures indicating yards upon the indicator-dial number, in theexample of my improvement shown, from zero to 480. Assuming that it isdesired to place three hundred and sixty yards upon the spool, theclamping-nut C is loosened and the indica` tor-dial is rotated from Zeroprogressively t0- ward the number 360 and until said number IOO isopposite a given point. In this instance such point is a toe d on alever d', which lever is fulcrumed upon a bracket d2, extending upwardlyfrom the bracket B3. The toc d occupies a position vertically directlyover the dial. At the zero-point on the dial is a notch d3. The dialhaving been set, as described, and the machine put in operation, thedial rotates toward the zero-point, and when it reaches the zero-pointthe toe d will drop into the notch d, which will result in operating astop-motion for the machine, to be presently described. The drivingmechanism between the drinn B and the indicator-dial is so timed thatthe rotation of the drum will deliver only the desired number of yardsof warp onto the spool that is provided for in the adjustment of thedial.

I will now describe the spindle for holdingl the spool upon which thewarp is wound and the means for operating the same. The warp afterleavingl the drum passes beneath a glass rod E, and thence between otherhorizontal glass rods c, mounted in suitable brackets c', extendingupwardly from the bed of the machine. After leaving the said rods itpasses directly onto a spool F. Said spool F, as shown in the example ofmy improvement illustrated in Fig. 1, comprises a continuous barrel withthe ordinary heads. It is mounted upon a vertical spindle F', and isclamped thereon so as to rot-ate therewith by means of a thumb-nutf. Thespindle F', and eonsequentlythe spool F, have a vertical reciprocatingmotion imparted to tl iem,where by the warp is wound evenly upon thespool from end to end, as required.

I wish to observe that by passing the warpthreads over thehorizontally-arranged drum, and thence between horizontally-arrangedrods, and thus to a vertically-arranged spool, the threads have nochance to stray or become uneven in tension, and the warp, whendelivered upon the spool, is kept in an even compact condition. This isdue to the fact that the warp after leaving said rods is turned ordeficcted, so that it is delivered from the horizontal and in a verticalplane.

I have shown means for imparting' a lvertical reeiprocation to thespindle F', consistingr of a lever F2, which lever is bifurcated, theend portions of the bifurcations being pivotally connected with linksF3, which latter are pivotally connected near their lower ends with aring f, loosely tittin in a collar f2-3, rigidly secured upon the lowerportion of the spindle F. The lever F2 is fulcrumed in a bracket F4,which bracket is secured upon a portion of the frame of the machine.Said bracket is provided with a horizontally-extending slot f2?, intowhich slot extends a pin f 3, as here shown, mounted upon a sleeve f '1,surrounding the lever l"- and secured thereto. Upon the lever F2 is aroller or bowl f5, which roller or bowl extends into an inclinedcamgroovef, formed circuinferentiallyin a camwheel f7. When thecam-wheel f T is rotated,

the cam-groove f, acting upon the roller or bowl f, will cause the leverF2 to be swung up and down, and thus cause a vertical reciprocation ofthe spindle and spool.

It is sometimes desirable to vary the degree of reeiprocation of thespindle and spool. This may be accomplished either by varying theposition which the roller or bowl will occupy on the lever F2, so as tovary the point of application of power, or by shifting` the fulcrum ofthe lever. This latter may be accomplished by loosening the sleeve f1and sliding it along upon the lever, so as to vary the position whichthe fulerum-pin fwilloccupy in the slot f2.

The cam-wheel f7 is mounted upon a vertically-extending shaft f3. Uponsaid shaft and secured to the cam-wheel is a gear-wheel f, whichgear-wheel meshes with a pinion f1", mounted upon a shaft f, upon whichshaft is also mounted a gear-wheel f, deriving motion from a gear-wheelf 13, mounted upon a vertically-extending shaft f1", journaled insuitable bearings in the frame. The shaft f1" has upon it anothergear-wheel f 15, which gearwheel meshes with a gear-wheel f1, having asliding' or feathered connection with the spindle F'. Rotary motionimparted to the shaft f1" therefore not only causes the rotary motion ofthe spindle F', but also results through the intermediate mechanism inimparting vertical reciprocation to said spindle.

I have shown friction-gearing for transmitting motion to thc shaft f 14.This frietion-gearing comprises a disk g on the shaft f"1 and afriction-wheel g' on a horizontallyextending main or driving shaft G.The shaft G near one end has a loose bearing in a bracket g2, extendingdownwardly from the frame of the machine. Near its other end it isjournaled in a bearing g3, pivoted upon the frame of the machine. Thisconstruction admits of a vertical rockingniovement of the shaft G.

The friction-wheel g' has a feathered or slidingl connection with theshaft G, so that it may be moved nearer to or farther from the axis ofrotation of the disk g. -ly thus moving it the speed of rotation of thespindle and the reciproeation thereof may be varied as desired, as bymoving the wheel g nearer to the center of the disk g the speed will heincreased, and by moving it outwardly or toward the periphery of thefriction-disk g the speed will be decreased.

I have shown a convenient means for shifting the wheel g', consisting ina lever G', fulcrumed in the frame of the machine, and provided near itslower end with a yoke which engages an annular groove g", formed on thehub of the wheel g'. The lever G' may engage notches in a lock-bracketGX, secured upon the frame of the machine, so as to maintain the wheelg' in any position into which it may be adjusted. Of course the hub ofthe wheel y rotates freely in the yoke of the lever.

-j upon-the rod J5.

Rotary motion is imparted to the shaft G by means of a belt passing overa fast pulley G2 on the shaft. Upon said shaft also is a loose pulleyG5.

I have shown a weight G4 supported from the bearing g5. The weight G4operates to rock the shaft downward, so as to force the friction-wheelgalways into close contact with the disk g.

I have shown an electrically-operatin g stopmotion for stopping themachine when the proper quantity of warp has been received upon thespool. When the toe d upon the lever d drops into the notch at thezeropoint on the dial C, a rod H, suspended from said lever, also falls.Upon the lower end of said rod is 'a circuit-closer h. Thiscircuitcloser, when the rod II falls, contacts with two contact-pieces hin a local circuit controlled by a battery I. Circuit is thus closedupon an electro-magnet I', thus energizing the magnet. When the magnetis energized, an armature I2 is attracted. To the armature I2 isconnected a rod I3. The rod I3, as shown 'more clearly in Fig. 5, isprovided near its upper end with a projection t'. Said rod may slidevertically in suitable bearings in an upright I4. The upright I4 isprovided with two transversely-extending apertures 'i2 Referring moreparticularly to Figs. 2, 3, and 7, J designates a rod adapted to move toandfro through the aperture 5 in the upright I4. Longitudinal movementis imparted to the rod J from an eccentric J on the shaft G by means ofan eccentric-rod J2, one end of which connects with one arm of abellcrank lever J 5, and the other arm of which has connected to it therod J The bell-crank lever J 5 is fulcrumed upon the frame B2. The otherend of the rod J is connected by means of a clamp J4 to a rod J5, whichrod is adapted to be moved to and fro through the opening t2 in theupright I4, and also through a suitable opening in a bracket 35,extending upwardly from the frame B2. The clamp J4 has a looseconnection with the rod J5, so that it may, under certain circumstances,slide upon said rod. It is caused, however, to impart longitudinalmovement to the rod J5 by a spring J 5, which surrounds the rod J5 andis interposed between the clamp J4 and a collar The resistance of thisspring is such that when the passage of the rod J5 is unobstructedthrough the aperture t2 in the upright I4 the clalnp J4 will causelongitudinal movement of the rod J Then the armature I2 is attracted, ashas been described, and the rod I3 is brought downward, the projectionst thereof will be brought opposite the aperture t2, and thus preventlongitudinal movement of the rod J5. A continued reciprocation ot' therod J is, however, permitted, owing to the spring J 6.

Pivoted upon the rod J 5 is a lever J T, which lever has a looseconnection near its lower end, as shown, being held between pins, withthe clamp J4. Vhen the rods J J5 are reciprocating in unison, this levermoves with the rods; but when the movement of the rod J 5 has beenstopped the lever J 7 is, by the movement of the rod J, rocked upon itsfulcrum. It then operates to raise one end of a trip L, provided with atooth l, engagingaprojection Z4 upon a lever L. The lever L 'isfulcrumed near the base of the frame B2, and has connected to it one endof a belt-shifter rod L2, which belt-shifter rod carries at its otherend a belt-shifter L5, by which the belt may be shifted from the fast orloose pulley, or vice versa. In the operation just described the belt isshifted to the loose pulley, and the machine is therefore instantlystopped. The movement of the lever in one direction or in the directionto stop the machine is facilitated by a spring L4, connected thereto andto the frame B2. The machine is again started by rotating the dial Csufiiciently to raise the toe d out of the notch d5, and again operatingthe lever L to engage it with the trip L.

I sometimes `desire to wind warps for selvages on this machine, and todo that I employtwo spools F, as shown more clearly in Fig. G, placingone above the other upon the spindle F and substitute two sets of rodse, through each of which a selvage-warppasses and is guided to each ofthe spools F. By this means both selvage-warps maybe woundsimultaneously and separately and with no more difficulty than isincident to the winding of a simple warp.

Any kind of suitable stop-motion may be employed which will stop themachine upon the breaking of single warp-threads at the creel from whichthey are delivered. Such, stop-motions are in common use and do not needdescription or illustration here.

VhatI claim as my invention, and desire to secure by Letters Patent, is-
